    text-decoration: none;
    overflow: hidden;
    display: block;
    padding: 0px;
    font-size: 16px !important;
    font-family: "Noto Kufi Arabic" !important;
    color: #ffffff !important;
    border-bottom: 0px !important;
 }

#wpsm_accordion_876 .wpsm_panel-body {
    background-color: #ffffff !important;
    color: #000000 !important;
    border-top-color: #147d6e !important;
    font-size: 15px !important;
    font-family: "Noto Kufi Arabic" !important;
    overflow: hidden;
    border: 2px solid #147d6e !important;
